Meguiar's #43 Marine Boat Soap is a marine boat soap option for routine boat and rv washing while preserving existing wax. Mariners Warehouse SKU 55973, manufacturer code M4364, supplies one 64 oz container. Clean ordinary boat or RV grime with a sudsing marine wash designed to preserve existing wax protection.
The pH-balanced formula supports routine fiberglass and gelcoat washing. Its role is maintenance cleaning rather than abrasive restoration or a dedicated waterline-stain treatment. Check the boat or RV finish and existing coating care requirements. Fiberglass and gelcoat are identified uses; specialty materials require their own approval.
This is a single-container listing. Compare the amount you expect to use and the room available for storage before choosing a larger package or case. The wash tools, bucket, measuring container and drying materials needed for your chosen procedure are separate unless explicitly confirmed in the listing.
Use the exact M4364 bottle dilution. A numerical US-label dose was not verified for this batch. Follow the delivered M4364 wash-and-rinse directions, with suitable clean wash tools and water. No full-sun wipe-off shortcut, numeric dwell time or pressure-washer setting is supplied. Inspect remaining marks after washing and identify their cause before moving to a different cleaning or restoration product.
